Share on facebook Facebook Share on twitter Twitter Share on pinterest Pinterest Share on whatsapp WhatsApp Share on email Email UPDATE: In March 2020, the decision was taken to terminate further in-house development of the MTD201 programme with immediate effect although the asset remains available for licensing. All activities connected with MTD201 have been wound down expeditiously and the manufacturing facilities in Bilbao have been closed. Following the termination of in-house development of MTD201, the Company realigned its strategy towards exploiting its Q-Sphera technology more broadly.Original Article belowIn my article listing the somatostatin analogues and their drug delivery systems pipeline (click here), there has been a very interesting development in a product called Q-Sphera (was previously known as Q-Octreotide).  In a press release, it was announced that an unnamed 'pharma giant'…

Neuroendocrine Cancer: a needle in a haystack?

Neuroendocrine Cancer: a needle in a haystack?

Patient Advocacy
Reviewed and edited 26th September 2021It's no secret that Neuroendocrine Cancer can be difficult to diagnose. Although earlier diagnosis is improving (as reported in the SEER database report issued in 2017), there is still a lot of ground to cover. There are a number of reasons why these Neoplasms are often difficult to correctly and quickly diagnose including but not limited to: - they grow silently, they often produce vague symptoms which can be mistaken for much more common illnesses, and their complexity is not fully understood.I may use the following terms in this post:Neuroendocrine Neoplasm (NENs) - a combination term for both well differentiated Neuroendocrine Tumours  (NETs) and Neuroendocrine Carcinomas (NECs)I wanted to cover two different aspects of the problem of finding NENs. Firstly, in finding the primary tumour…

Neuroendocrine Cancer Clinical Trial – Lutetium-177 OPS-201 (Satoreotide)

Neuroendocrine Cancer Clinical Trial – Lutetium-177 OPS-201 (Satoreotide)

Clinical Trials
This post is currently parked due to anecdotal reports that Ipsen is withdrawing from the radiopeptide market.  It's possible this product may continue under another manufacturer.  Will update when known. What is Lutetium-177 OPS-201? This is a 'next generation' Peptide receptor radionuclide therapy (PRRT) or more specifically the radiopharmaceutical that binds to both activated and unactivated somatostatin receptors which are upregulated on these tumours. There is far higher binding via this mechanism than standard octreotate. The technical name of the radiopharmaceutical is Satoreotide tetraxetan lutetium-177 (author's note, I'm guessing but it could be a variant of Lanreotide).  It was once named JR11. What's the difference to the current approved therapy?  Conventional PRRT (e.g. Lutathera, Lu177 Dotatate) is based on a somatostatin receptor 'agonist' approach, whereas 177Lu Ops 201 Satoreotide is…
